There is a property LiveScroll that turns on and off "live scrolling". Live scrolling, from what I can tell, is basically when you just move the scrollbar grab up and down the app and the document/contents automatically move along with it.
There are *no* applications that don't implement this any more. As such, it I would consider this to be a feature that is no longer needed, and we can simply our code if we get rid of it.
I have confirmed what Live Scroll does. See http://api.libreoffice.org/docs/idl/ref/servicecom_1_1sun_1_1star_1_1awt_1_1UnoControlScrollBarModel.html#a766c49dea539a10248b6300e4e909c65
Property is boolean LiveScroll
specifies the scrolling behavior of the control.
TRUE means, that when the user moves the slider in the scroll bar, the content of the window is updated immediately. FALSE means, that the window is only updated after the user has released the mouse button.
Nobody uses this, surely?
This is the kind of options that typically makes (when turned off) the application much easier to use over slow displays (such as e.g. a remote X session over an Internet connection of typical ADSL speed).
I don't find where in the options UI it can be turned off, though.
Related are BASEPROPERTY_LIVE_SCROLL and DRAGFULL_OPTION_SCROLL and the Window/Drag option in officecfg, GetDragFullOptions and SvtTabAppearanceCfg::GetDragMode
I set status to NEW since this is an enhancement request.
UX-advise needed to see if removing this feature is worth it.
As this is part of the API, can't remove this.
